Slskd on RPI4 running OSMC

Hello!
Has someone managed to get slskd (a Soulseek daemon) running on a PI4 running OSMC?
I get it to run Raspbian Bullseye 32 bit, but not on OSMC. I’ve been getting a lot of help from the developer, but we can’t figure out what the underlying issue is.

At first we figured that it might be missing musl-libraries, and then he created new binaries with musl included, but still no luck.
My guess is that it might have anything to do with the fact that OSMC for Raspberry comes with 64-bit kernels and 32-bit userland (I might be remembering wrong).

Here’s the output from the shell:

osmc@Rubicon:~/System/slskd$ unzip slskd-0.16.2-linux-musl-arm.zip

And for ar64-bit:

osmc@Rubicon:~/System/slskd$ unzip slskd-0.16.2-linux-musl-arm64.zip

Is there anyone that has any idea of what the problem might be?
“Filen eller katalogen finns inte” means “File or folder not found”
